Elite event ee-gh7 and methods and kits for identifying such event in biological samples

ABSTRACT

The invention provides specific transgenic cotton plants, plant material and seeds, characterized in that these products harbor a specific herbicide tolerance transformation event at a specific location in the cotton genome. Tools are also provided which allow rapid and unequivocal identification of the event in biological samples.

FIELD OF THE INVENTION

This invention relates to novel nucleic acids and transgenic cottonplants, plant material and seeds, characterized by harboring a specifictransformation event, particularly by the presence of genes encodingproteins that confer herbicide tolerance, at a specific location in thecotton genome. The cotton plants of the invention combine the herbicidetolerance phenotype with an agronomic performance, genetic stability andfunctionality in different genetic backgrounds equivalent to thecorresponding non-transformed cotton genetic background in the absenceof herbicide(s). This invention further provides methods and kits foridentifying the presence of plant material comprising specificallytransformation event EE-GH7 in biological samples.

BACKGROUND OF THE INVENTION

The phenotypic expression of a transgene in a plant is determined bothby the structure of the gene or genes itself and by its or theirlocation in the plant genome. At the same time the presence of thetransgenes or “foreign DNA” at different locations in the genome willinfluence the overall phenotype of the plant in different ways. Theagronomically or industrially successful introduction of a commerciallyinteresting trait in a plant by genetic manipulation can be a lengthyprocedure dependent on different factors. The actual transformation andregeneration of genetically transformed plants are only the first in aseries of selection steps, which include extensive geneticcharacterization, introgression, and evaluation in field trials,eventually leading to the selection of an elite event.

The unequivocal identification of an elite event is becomingincreasingly important in view of discussions on Novel Food/Feed,segregation of GMO and non-GMO products and the identification ofproprietary material. Ideally, such identification method is both quickand simple, without the need for an extensive laboratory set-up.Furthermore, the method should provide results that allow unequivocaldetermination of the elite event without expert interpretation, butwhich hold up under expert scrutiny if necessary. Specific tools for usein the identification of elite event EE-GH7 in biological samples aredescribed herein.

In this invention, EE-GH7 has been identified as an elite event from apopulation of transgenic cotton plants in the development of herbicidetolerant cotton (Gossypium hirsutum) comprising a gene coding forglyphosate tolerance combined with a gene conferring tolerance to4-hydroxy phenylpyruvate dioxygenase (HPPD) inhibitors, each undercontrol of a plant-expressible promoter.

Planting double-herbicide-tolerant cotton EE-GH7 varieties providesgrowers with new options for weed control using Isoxaflutole (IFT)and/or glyphosate herbicide. Glyphosate is widely used in cotton andother agricultural production systems. IFT herbicide offers analternative weed control option for the cotton grower to help manageproblem weed species and as an alternative mode of action tool to helpslow the spread of herbicide resistant weeds. With IFT, a new mode ofaction is introduced in cotton that is efficacious against many weedscurrently found in cotton fields.

Cotton plants comprising a herbicide tolerance gene have been disclosedin the art. WO2007/017186 describes a glyphosate tolerant elite cottonevent comprising an epsps gene. WO2013/026740 describes cotton plantscomprising both an hppd and an epsps gene conferring tolerance in thegreenhouse and in the field. WO2013/026740 also describes cotton plantscomprising both an hppd and an epsps gene which are introduced in the 3′flanking region of the elite event described in WO2008/151780 comprisingan insect resistance gene. However, none of the prior art disclosuresteach or suggest an elite event comprising both a gene coding forglyphosate tolerance combined with a gene conferring tolerance to HPPDinhibitors which can be used in a flexible way with or without an insectresistance gene.

It is known in the art that getting a commercial herbicide tolerantelite transformation event in cotton plants with acceptable agronomicperformance, and providing sufficient herbicide tolerance, certainly to2 different classes of herbicides, is by no means straightforward.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION

In this invention, EE-GH7 has been identified as an elite event from apopulation of transgenic cotton plants in the development of herbicidetolerant cotton (Gossypium hirsutum) comprising a gene coding forglyphosate tolerance combined with a gene conferring tolerance to4-hydroxy phenylpyruvate dioxygenase (HPPD) inhibitors, each undercontrol of a plant-expressible promoter.

The incorporation of a recombinant DNA molecule in the plant genometypically results from transformation of a cell or tissue. Theparticular site of incorporation is usually due to random integration.

The DNA introduced into the plant genome as a result of transformationof a plant cell or tissue with a recombinant DNA or “transforming DNA”,and originating from such transforming DNA is hereinafter referred to as“foreign DNA” comprising one or more “transgenes”. The transgenes ofEE-GH7 are the glyphosate and HPPD inhibitor herbicide tolerance genes.“Plant DNA” in the context of the present invention will refer to DNAoriginating from the plant which is transformed. Plant DNA will usuallybe found in the same genetic locus in the corresponding wild-type plant.The foreign DNA can be characterized by the location and theconfiguration at the site of incorporation of the recombinant DNAmolecule in the plant genome. The site in the plant genome where arecombinant DNA has been inserted is also referred to as the “insertionsite” or “target site”. Insertion of the recombinant DNA into the regionof the plant genome referred to as “pre-insertion plant DNA” can beassociated with a deletion of plant DNA, referred to as “target sitedeletion”. A “flanking region” or “flanking sequence” as used hereinrefers to a sequence of at least 20 bp, preferably at least 50 bp, andup to 5000 bp of DNA different from the introduced DNA, preferably DNAfrom the plant genome which is located either immediately upstream ofand contiguous with or immediately downstream of and contiguous with theforeign DNA. Transformation procedures leading to random integration ofthe foreign DNA will result in transformants with different flankingregions, which are characteristic and unique for each transformant. Whenthe recombinant DNA is introduced into a plant through traditionalcrossing, its insertion site in the plant genome, or its flankingregions will generally not be changed.

An “isolated nucleic acid (sequence or molecule)” or “isolated DNA(sequence or molecule)”, as used herein, refers to a nucleic acid or DNA(sequence or molecule) which is no longer in the natural environment itwas isolated from, e.g., the nucleic acid sequence in another bacterialhost or in a plant genome, or a nucleic acid or DNA fused to DNA ornucleic acid from another origin, such as when contained in a chimericgene under the control of a plant-expressible promoter. Any nucleic acidor DNA of this invention, including any primer, can also benon-naturally-occurring, such as a nucleic acid or DNA with a sequenceidentical to a sequence occurring in nature, but having a label (missingfrom the naturally-occurring counterpart), or with a sequence having atleast one nucleotide addition or replacement or at least one internalnucleotide deletion compared to a naturally-existing nucleotide, or witha sequence having a sequence identity below 100% (not identical) to anaturally-existing nucleic acid or DNA or a fragment thereof, or anucleic acid or DNA with a sequence consisting of nucleotide sequencesfrom different origins that do not occur together in nature (a chimericor hybrid DNA), or a man-made synthetic nucleic acid or DNA with asequence different from the natural nucleic acid or DNA or a fragmentthereof.

An event is defined as a (artificial) genetic locus that, as a result ofgenetic engineering, carries a foreign DNA or transgene comprising atleast one copy of a gene of interest or of the genes of interest. Thetypical allelic states of an event are the presence or absence of theforeign DNA. An event is characterized phenotypically by the expressionof the transgene. At the genetic level, an event is part of the geneticmake-up of a plant. At the molecular level, an event can becharacterized by the restriction map (e.g., as determined by Southernblotting), by the upstream and/or downstream flanking sequences of thetransgene, the location of molecular markers and/or the molecularconfiguration of the transgene. Usually transformation of a plant with atransforming DNA comprising at least one gene of interest leads to apopulation of transformants comprising a multitude of separate events,each of which is unique. An event is characterized by the foreign DNAand at least one of the flanking sequences.

An elite event, as used herein, is an event which is selected from agroup of events, obtained by transformation with the same transformingDNA, based on an optimal trait efficacy and superior expression,stability of the transgene(s) and its compatibility with optimalagronomic characteristics of the plant comprising it. Thus the criteriafor elite event selection are one or more, preferably two or more,advantageously all of the following:

-   -   a) trait efficacy;    -   b) that the presence of the foreign DNA does not compromise        other desired characteristics of the plant, such as those        relating to agronomic performance or commercial value;    -   c) that the event is characterized by a well-defined molecular        configuration which is stably inherited and for which        appropriate tools for identity control can be developed;    -   d) that the gene(s) of interest show(s) a correct, appropriate        and stable spatial and temporal phenotypic expression, at a        commercially acceptable level in a range of environmental        conditions in which the plants carrying the event are likely to        be exposed in normal agronomic use.

It is preferred that the foreign DNA is associated with a position inthe plant genome that allows easy introgression into desired commercialgenetic backgrounds.

The status of an event as an elite event is confirmed by introgressionof the elite event in different relevant genetic backgrounds andobserving compliance with one, two, three or all of the criteria e.g.a), b) and c) and d) above.

An “elite event” thus refers to a genetic locus comprising a foreignDNA, which meets the above-described criteria. A plant, plant materialor progeny such as seeds can comprise one or more elite events in itsgenome.

The tools developed to identify an elite event or the plant or plantmaterial comprising an elite event, or products which comprise plantmaterial comprising the elite event, are based on the specific genomiccharacteristics of the elite event, such as, a specific restriction mapof the genomic region comprising the foreign DNA, molecular markers orthe sequence of the flanking region(s) of the foreign DNA.

Once one or both of the flanking regions of the foreign DNA have beensequenced, primers and probes can be developed which specificallyrecognize this (these) sequence(s) in the nucleic acid (DNA or RNA) of asample by way of a molecular biological technique. For instance a PCRmethod can be developed to identify the elite event in biologicalsamples (such as samples of plants, plant material or productscomprising plant material). Such a PCR is based on at least two specific“primers”, one recognizing a sequence within the 5′ or 3′ flankingregion of the elite event and the other recognizing a sequence withinthe foreign DNA. The primers preferably have a sequence of between 15and 35 nucleotides which under optimized PCR conditions “specificallyrecognize” a sequence within the 5′ or 3′ flanking region of the eliteevent and the foreign DNA of the elite event respectively, so that aspecific fragment (“integration fragment” or discriminating amplicon) isamplified from a nucleic acid sample comprising the elite event. Thismeans that only the targeted integration fragment, and no other sequencein the plant genome or foreign DNA, is amplified under optimized PCRconditions.

PCR primers suitable for the invention may be the following:

-   -   oligonucleotides ranging in length from 17 nt to about 200 nt,        comprising a nucleotide sequence of at least 17 consecutive        nucleotides, preferably 20 consecutive nucleotides, selected        from the plant DNA in the 5′ flanking sequence (SEQ ID No. 1        from nucleotide 1 to nucleotide 1217) at their 3′ end (primers        recognizing 5′ flanking sequences); or    -   oligonucleotides ranging in length from 17 nt to about 200 nt,        comprising a nucleotide sequence of at least 17 consecutive        nucleotides, preferably 20 consecutive nucleotides, selected        from the plant DNA in the 3′ flanking sequence (complement of        SEQ ID No. 1 from nucleotide 8033 to nucleotide 9328) at their        3′ end (primers recognizing 3′ flanking sequences); or    -   oligonucleotides ranging in length from 17 nt to about 200 nt,        comprising a nucleotide sequence of at least 17 consecutive        nucleotides, preferably 20 consecutive nucleotides, selected        from the inserted DNA sequences (complement of SEQ ID No. 1 from        nucleotide 1218 to nucleotide 8032) at their 3′ end (primers        recognizing foreign DNA); or    -   oligonucleotides ranging in length from 17 nt to about 200 nt,        comprising a nucleotide sequence of at least 17 consecutive        nucleotides, preferably 20 consecutive nucleotides, selected        from the inserted DNA sequences (SEQ ID No. 1 from nucleotide        1218 to nucleotide 8032) at their 3′ end (primers recognizing        foreign DNA); or    -   suitable oligonucleotides ranging in length from 17 nt to about        200 nt, comprising a nucleotide sequence of at least 17        consecutive nucleotides, preferably 20 consecutive nucleotides,        selected from the nucleotide sequence of the inserted DNA        fragment or its complement (SEQ ID No. 1 from nucleotide 1218 to        nucleotide 8032).

It will be understood that primers recognizing the 5′ flanking sequencescan be used in a PCR reaction together with primers recognizing theforeign DNA which are selected from the complement of SEQ ID No. 1 fromnucleotide 1218 to nucleotide 8032, whereas primers recognizing the 3′flanking sequences can be used in a PCR reaction together with primersrecognizing the foreign DNA which are selected from directed to SEQ IDNo. 1 from nucleotide 1218 to nucleotide 8032.

The primers may of course be longer than the mentioned 17 consecutivenucleotides, and may, e.g., be 20, 21, 30, 35, 50, 75, 100, 150, 200 ntlong or even longer. The primers may entirely consist of nucleotidesequence selected from the mentioned nucleotide sequences of flankingsequences and foreign DNA sequences. However, the nucleotide sequence ofthe primers at their 5′ end (i.e. outside of the 3′-located 17consecutive nucleotides) is less critical. Thus, the 5′ sequence of theprimers may comprise or consist of a nucleotide sequence selected fromthe flanking sequences or foreign DNA, as appropriate, but may containseveral (e.g., 1, 2, 5, or 10) mismatches. The 5′ sequence of theprimers may even entirely be a nucleotide sequence unrelated to theflanking sequences or foreign DNA, such as, e.g., a nucleotide sequencerepresenting one or more restriction enzyme recognition sites, or suchas nucleotide sequences capable of binding other oligonucleotides, suchas labelled oligonucleotides, such as FRET cassettes (LGC genomics; seeSemagn et al., 2014, Mol Breeding 33:1-14, and U.S. Pat. No. 7,615,620).Such unrelated sequences or flanking DNA sequences with mismatchesshould preferably not be longer than 100, more preferably not longerthan 50 or even 25 nucleotides. The primers can also be modified with alabel, such as a fluorescent label.

Moreover, suitable primers may comprise or consist (essentially) of anucleotide sequence at their 3′ end spanning the joining region betweenthe plant DNA derived sequences and the foreign DNA sequences (locatedat nucleotides 1217 and 1218 in SEQ ID No 1 and nucleotides 8032 and8033 in SEQ ID No 1) provided the mentioned 3′-located 17 consecutivenucleotides are not derived exclusively from either the foreign DNA orplant-derived sequences in SEQ ID No. 1.

It will also be immediately clear to the skilled artisan that properlyselected PCR primer pairs should also not comprise sequencescomplementary to each other.

Primers and probes according to the invention can be labelled, such as,for example, with fluorescent labels or quenchers as described elsewhereherein.

Primers according to the invention can have unrelated sequences at the5′ end. Probes according to the invention can have unrelated sequencesat the 5′ end and/or at the 3′ end. Such unrelated sequences can, forexample, be sequences that are designed to bind to secondary primers, orcan be sequences comprising restriction sites, or can be any unrelatedsequences.

For the purpose of the invention, the “complement of a nucleotidesequence represented in SEQ ID No: X” is the nucleotide sequence whichcan be derived from the represented nucleotide sequence by replacing thenucleotides with their complementary nucleotide according to Chargaff'srules (A⇔T; G⇔C) and reading the sequence in the 5′ to 3′ direction,i.e., in opposite direction of the represented nucleotide sequence.

Examples of suitable primers are the oligonucleotide sequences of SEQ IDNo 3, SEQ ID no. 5 or SEQ ID No. 11 (5′ flanking sequence recognizingprimer), or SEQ ID No 4, SEQ ID No. 6 (foreign DNA recognizing primerfor use with the 5′ flanking sequence recognizing primers).

Preferably, the amplified fragment has a length of between 50 and 500nucleotides, such as a length between 50 and 150 nucleotides. Thespecific primers may have a sequence which is between 80 and 100%identical to a sequence within the 5′ or 3′ flanking region of the eliteevent and the foreign DNA of the elite event, respectively, provided themismatches still allow specific identification of the elite event withthese primers under optimized PCR conditions. The range of allowablemismatches however, can easily be determined experimentally and areknown to a person skilled in the art.

Detection of integration fragments can occur in various ways, e.g., viasize estimation after gel analysis. The integration fragments may alsobe directly sequenced. Other sequence specific methods for detection ofamplified DNA fragments are also known in the art. Amplified DNAfragments can also be detected using labelled sequences and detection ofthe label. For example, a labelled probe can be included in the reactionmixture which specifically binds to the amplified fragment. The labelledprobe (FRET hybridization probe) can comprise a fluorescent label and aquencher, such that FRET cassette is no longer quenched and emitsfluorescence when bound to the PCR product. Alternatively, a labelledFRET cassette, i.e. an oligonucleotide labelled with a fluorescent labeland a quencher, can be included in the reaction mixture whichspecifically binds one of the primers in the reaction mixture, such as aFRET cassette directed to a 5′ extension of the primer used in thereaction mixture (see, e.g., see Semagn et al., 2014, Mol Breeding33:1-14, and U.S. Pat. No. 7,615,620). Fluorescence can be measuredusing methods known in the art. Fluorescence can be measured real-time,i.e. during each cycle of the PCR reaction. Fluorescence can also bemeasured at the end of the PCR reaction.

As the sequence of the primers and their relative location in the genomeare unique for the elite event, amplification of the integrationfragment will occur only in biological samples comprising (the nucleicacid of) the elite event. Preferably when performing a PCR to identifythe presence of EE-GH7 in unknown samples, a control is included of aset of primers with which a fragment within a “housekeeping gene” of theplant species of the event can be amplified. Housekeeping genes aregenes that are expressed in most cell types and which are concerned withbasic metabolic activities common to all cells. Preferably, the fragmentamplified from the housekeeping gene is a fragment which is larger thanthe amplified integration fragment. Depending on the samples to beanalyzed, other controls can be included.

Standard PCR protocols are described in the art, such as in “PCRApplications Manual” (Roche Molecular Biochemicals, 2nd Edition, 1999)and other references. The optimal conditions for the PCR, including thesequence of the specific primers, are specified in a “PCR (or PolymeraseChain Reaction) Identification Protocol” for each elite event. It ishowever understood that a number of parameters in the PCR IdentificationProtocol may need to be adjusted to specific laboratory conditions, andmay be modified slightly to obtain similar results. For instance, use ofa different method for preparation of DNA may require adjustment of, forinstance, the amount of primers, polymerase and annealing conditionsused. Similarly, the selection of other primers may dictate otheroptimal conditions for the PCR Identification Protocol. Theseadjustments will however be apparent to a person skilled in the art, andare furthermore detailed in current PCR application manuals such as theone cited above.

Alternatively, specific primers can be used to amplify an integrationfragment that can be used as a “specific probe” for identifying EE-GH7in biological samples. Contacting nucleic acid of a biological sample,with the probe, under conditions which allow hybridization of the probewith its corresponding fragment in the nucleic acid, results in theformation of a nucleic acid/probe hybrid. The formation of this hybridcan be detected (e.g., via labeling of the nucleic acid or probe),whereby the formation of this hybrid indicates the presence of EE-GH7.Such identification methods based on hybridization with a specific probe(either on a solid phase carrier or in solution) have been described inthe art. The specific probe is preferably a sequence which, underoptimized conditions, hybridizes specifically to a region within the 5′or 3′ flanking region of the elite event and preferably also comprisingpart of the foreign DNA contiguous therewith (hereinafter referred to as“specific region”). Preferably, the specific probe comprises a sequenceof between 50 and 500 bp, preferably of 100 to 350 bp which is at least80%, preferably between 80 and 85%, more preferably between 85 and 90%,especially preferably between 90 and 95%, most preferably between 95%and 100% identical (or complementary) to the nucleotide sequence of aspecific region. Preferably, the specific probe will comprise a sequenceof about 15 to about 100 contiguous nucleotides identical (orcomplementary) to a specific region of the elite event.

Oligonucleotides suitable as PCR primers for detection of the eliteevent EE-GH7 can also be used to develop a PCR-based protocol todetermine the zygosity status of plants containing the elite event. Tothis end, two primers recognizing the wild-type locus before integrationare designed in such a way that they are directed towards each other andhave the insertion site located in between the primers. These primersmay be primers specifically recognizing the 5′ and 3′ flanking sequencescontained within SEQ ID No. 1. These primers may also be primersspecifically recognizing the 5′ or 3′ flanking sequence. This set ofprimers, together with a third primer complementary to transforming DNAsequences (foreign DNA) allows simultaneous diagnostic PCR amplificationof the EE-GH7 specific locus, as well as of the wild type locus. If theplant is homozygous for the transgenic locus or the corresponding wildtype locus, the diagnostic PCR will give rise to a single PCR producttypical, preferably typical in length, for either the transgenic or wildtype locus. If the plant is hemizygous for the transgenic locus, twolocus-specific PCR products will appear, reflecting both theamplification of the transgenic and wild type locus.

Alternatively, to determine the zygosity status of plants containing theelite event, two primers recognizing the wild-type locus beforeintegration are designed in such a way that they are directed towardseach other, and that one primer specifically recognizes the 5′ or the 3′flanking sequences contained within SEQ ID No. 1, and that one primerspecifically recognizes the 3′ or the 5′ flanking sequences containedwithin SEQ ID No. 1, or specifically recognizes the target sitedeletion. For the current invention, particularly suitable primersrecognizing the wild type locus before integration are primerscomprising or consisting (essentially) of the nucleotide sequence of SEQID No 11 and SEQ ID No. 12. This set of primers, together with a thirdprimer complementary to transforming DNA sequences (foreign DNA), orcomplementary to transforming DNA sequences and the 5′ or 3′ flankingsequences contiguous therewith, and in a direction towards the primerwhich specifically recognizes the 5′ or the 3′ flanking sequences (suchas a primer comprising or consisting (essentially) of the nucleotidesequence of SEQ ID No 13, which is in a direction towards the primercomprising or consisting (essentially) of the nucleotide sequence of SEQID No 11) allow simultaneous diagnostic PCR amplification of the EE-GH7specific locus, as well as of the wild type locus. If the plant ishomozygous for the transgenic locus or the corresponding wild typelocus, the diagnostic PCR will give rise to a single PCR product typicalfor either the transgenic or wild type locus. If the plant is hemizygousfor the transgenic locus, two locus-specific PCR products will appear,reflecting both the amplification of the transgenic and wild type locus.

Detection of the PCR products typical for the wild-type and transgeniclocus can be based on determination of the length of the PCR productswhich can be typical for the wild-type and transgenic locus.Alternatively, detection of the PCR products typical for the wild-typeand transgenic locus can be performed by modification of the primerspecific for the target site deletion and by modification of the primerspecific for the foreign DNA, and detection of incorporation into a PCRproduct of the modified primers. For example, the primer specific forthe target site deletion and the primer specific for the foreign DNA canbe labelled using a fluorescent label, wherein the labels are differentfor the two primers. Fluorescence can be detected when the primer isincorporated into a PCR product. If the plant is homozygous for thetransgenic locus or the corresponding wild type locus, fluorescence canbe detected of the label of the primer specific for the foreign DNA onlyor of the primer specific for the target site deletion only. If theplant is hemizygous for the transgenic locus, fluorescence can bedetected of both the label of the primer specific for the foreign DNAand of the primer specific for the target site deletion, reflecting boththe amplification of the transgenic and wild type locus.

Alternatively, the primer specific for the target site deletion and theprimer specific for the foreign DNA can have a 5′ extension whichspecifically bind a labelled FRET cassette, i.e. an oligonucleotidelabelled with a fluorescent label and a quencher, wherein the 5′extension and the corresponding FRET cassettes are different for the twoprimers (see, e.g., see Semagn et al., 2014, Mol Breeding 33:1-14, andU.S. Pat. No. 7,615,620). Fluorescence can be detected when the primeris incorporated into a PCR product and, subsequently, the FRET cassetteis incorporated in the PCR product. If the plant is homozygous for thetransgenic locus or the corresponding wild type locus, fluorescence canbe detected of the FRET cassette specifically binding to the primerspecific for the foreign DNA only or of the FRET cassette specificallybinding to the primer specific for the target site deletion only. If theplant is hemizygous for the transgenic locus, fluorescence can bedetected of both of the FRET cassette specifically binding to the primerspecific for the foreign DNA and of the FRET cassette specificallybinding to the primer specific for the target site deletion, reflectingboth the amplification of the transgenic and wild type locus.

If the plant is homozygous for the transgenic locus or the correspondingwild type locus, the diagnostic PCR will give rise to a single PCRproduct typical, preferably typical in length, for either the transgenicor wild type locus. If the plant is hemizygous for the transgenic locus,two locus-specific PCR products will appear, reflecting both theamplification of the transgenic and wild type locus.

Alternatively, to determine the zygosity status of plants containing theelite event, presence of the event can be determined in a PCR reactionin a quantitative way as described in Example 2.2.2. To this end, twoprimers recognizing the transgenic are designed in such a way that theyare directed towards each other, wherein one primer specificallyrecognizes the 5′ or 3′ flanking sequence contained within SEQ ID No. 1,(such as a primer comprising or consisting (essentially) of thenucleotide sequence of SEQ ID No 5) and wherein one primer specificallyrecognizes the foreign DNA within SEQ ID no. 1 (such as a primercomprising or consisting (essentially) of the nucleotide sequence of SEQID No 6). This set of primers allows PCR amplification of the EE-GH7specific locus. The amplified DNA fragment can quantitatively bedetected using a labelled probe which is included in the reactionmixture which specifically binds to the amplified fragment (such as aprobe comprising or consisting (essentially) of the nucleotide sequenceof SEQ ID No 7). The labelled probe (FRET hybridization probe) cancomprise a fluorescent label and a quencher, such that FRET cassette isno longer quenched and emits fluorescence when bound to the PCR product.Fluorescence can be measured real-time, i.e. during each cycle of thePCR reaction, using methods known in the art. The PCR cycle at which thefluorescence exceeds a certain threshold level is a measure for theamount of EE-GH7 specific locus in the biological sample which isanalyzed, and the zygosity status can be calculated based on referencehomozygous and heterozygous samples.

Alternatively, zygosity status of plants comprising EE-GH7 can also bedetermined based on copy number analysis, using the Taqman chemistry andprinciples of Real-Time PCR. The alternative method will typicallyinclude a EE-GH7 specific reaction to quantify the EE-GH7 copy number,and a endogenous gene-specific reaction for normalization of the EE-GH7copy number. Samples containing the EE-GH7 event in a homozygous statewill have a relative copy number that is two-fold higher than hemizygoussamples. Azygous samples will not amplify the EE-GH7 sequence in such amethod.

Furthermore, detection methods specific for elite event EE-GH7 whichdiffer from PCR based amplification methods can also be developed usingthe elite event specific sequence information provided herein. Suchalternative detection methods include linear signal amplificationdetection methods based on invasive cleavage of particular nucleic acidstructures, also known as Invader™ technology, (as described e.g. inU.S. Pat. No. 5,985,557 “Invasive Cleavage of Nucleic Acids”, U.S. Pat.No. 6,001,567 “Detection of Nucleic Acid sequences by Invader DirectedCleavage”, incorporated herein by reference). To this end, the targetsequence is hybridized with a labeled first nucleic acid oligonucleotidecomprising the nucleotide sequence of SEQ ID No 1 from nucleotide 1218to nucleotide 1235 or its complement or said labeled nucleic acid probecomprising the nucleotide sequence of SEQ ID No 1 from nucleotide 8015to 8032 or its complement and is further hybridized with a secondnucleic acid oligonucleotide comprising the nucleotide sequence of SEQID No 1 from nucleotide 1200 to nucleotide 1217 or its complement orsaid labeled nucleic acid probe comprising the nucleotide sequence ofSEQ ID No 1 from nucleotide 8033 to nucleotide 8050 or its complement,wherein the first and second oligonucleotide overlap by at least onenucleotide. The duplex or triplex structure which is produced by thishybridization allows selective probe cleavage with an enzyme (Cleavase®)leaving the target sequence intact. The cleaved labeled probe issubsequently detected, potentially via an intermediate step resulting infurther signal amplification.

A “kit” as used herein refers to a set of reagents for the purpose ofperforming the method of the invention, more particularly, theidentification of the elite event EE-GH7 in biological samples or thedetermination of the zygosity status of EE-GH7 containing plantmaterial. More particularly, a preferred embodiment of the kit of theinvention comprises at least one or two specific primers, as describedabove for identification of the elite event, or three specific primers,or two specific primers and one specific probe, as described above forthe determination of the zygosity status. Optionally, the kit canfurther comprise any other reagent described herein in the PCRIdentification Protocol or any of the other protocols as describedherein for EE-GH7 detection. Alternatively, according to anotherembodiment of this invention, the kit can comprise a specific probe, asdescribed above, which specifically hybridizes with nucleic acid ofbiological samples to identify the presence of EE-GH7 therein.Optionally, the kit can further comprise any other reagent (such as butnot limited to hybridizing buffer, label) for identification of EE-GH7in biological samples, using the specific probe.

The kit of the invention can be used, and its components can bespecifically adjusted, for purposes of quality control (e.g., purity ofseed lots), detection of the presence or absence of the elite event inplant material or material comprising or derived from plant material,such as but not limited to food or feed products.

As used herein, “sequence identity” with regard to nucleotide sequences(DNA or RNA), refers to the number of positions with identicalnucleotides divided by the number of nucleotides in the shorter of thetwo sequences. The alignment of the two nucleotide sequences isperformed by the Wilbur and Lipmann algorithm (Wilbur and Lipmann, 1983,Proc. Nat. Acad. Sci. USA 80:726) using a window-size of 20 nucleotides,a word length of 4 nucleotides, and a gap penalty of 4.Computer-assisted analysis and interpretation of sequence data,including sequence alignment as described above, can, e.g., beconveniently performed using the sequence analysis software package ofthe Genetics Computer Group (GCG, University of Wisconsin BiotechnologyCenter). Sequences are indicated as “essentially similar” when suchsequences have a sequence identity of at least about 75%, particularlyat least about 80%, more particularly at least about 85%, quiteparticularly at least about 90%, especially at least about 95%, moreespecially at least about 98%, or at least about 99%. It is clear thatwhen RNA sequences are said to be essentially similar or have a certaindegree of sequence identity with DNA sequences, thymidine (T) in the DNAsequence is considered equal to uracil (U) in the RNA sequence. Also, itis clear that small differences or mutations may appear in DNA sequencesover time and that some mismatches can be allowed for the event-specificprimers or probes of the invention, so any DNA sequence indicated hereinin any embodiment of this invention for any 3′ or 5′ flanking DNA or forany insert or foreign DNA or any primer or probe of this invention, alsoincludes sequences essentially similar to the sequences provided herein,such as sequences hybridizing to or with at least 90%, 95%, 96%, 97%,98%, or at least 99% sequence identity to the sequence given for any 3′or 5′ flanking DNA, for any primer or probe or for any insert or foreignDNA of this invention.

The term “primer” as used herein encompasses any nucleic acid that iscapable of priming the synthesis of a nascent nucleic acid in atemplate-dependent process, such as PCR. Typically, primers areoligonucleotides from 10 to 30 nucleotides, but longer sequences can beemployed. Primers may be provided in double-stranded form, though thesingle-stranded form is preferred. Probes can be used as primers, butare designed to bind to the target DNA or RNA and need not be used in anamplification process.

The term “recognizing” as used herein when referring to specificprimers, refers to the fact that the specific primers specificallyhybridize to a nucleic acid sequence in the elite event under theconditions set forth in the method (such as the conditions of the PCRIdentification Protocol), whereby the specificity is determined by thepresence of positive and negative controls.

The term “hybridizing” as used herein when referring to specific probes,refers to the fact that the probe binds to a specific region in thenucleic acid sequence of the elite event under standard stringencyconditions. Standard stringency conditions as used herein refers to theconditions for hybridization described herein or to the conventionalhybridizing conditions as described by Sambrook et al., 1989 (MolecularCloning: A Laboratory Manual, Second Edition, Cold Spring HarborLaboratory Press, NY) which for instance can comprise the followingsteps: 1) immobilizing plant genomic DNA fragments on a filter, 2)prehybridizing the filter for 1 to 2 hours at 42° C. in 50% formamide,5×SSPE, 2×Denhardt's reagent and 0.1% SDS, or for 1 to 2 hours at 68° C.in 6×SSC, 2×Denhardt's reagent and 0.1% SDS, 3) adding the hybridizationprobe which has been labeled, 4) incubating for 16 to 24 hours, 5)washing the filter for 20 min. at room temperature in 1×SSC, 0.1% SDS,6) washing the filter three times for 20 min. each at 68° C. in 0.2×SSC,0.1% SDS, and 7) exposing the filter for 24 to 48 hours to X-ray film at−70° C. with an intensifying screen.

As used in herein, a biological sample is a sample of a plant, plantmaterial or products comprising plant material. The term “plant” isintended to encompass cotton (Gossypium hirsutum) plant tissues, at anystage of maturity, as well as any cells, tissues, or organs taken fromor derived from any such plant, including without limitation, any seeds,leaves, stems, flowers, roots, single cells, gametes, cell cultures,tissue cultures or protoplasts. “Plant material”, as used herein refersto material which is obtained or derived from a plant. Productscomprising plant material relate to food, feed or other products whichare produced using plant material or can be contaminated by plantmaterial. It is understood that, in the context of the presentinvention, such biological samples are tested for the presence ofnucleic acids specific for EE-GH7, implying the presence of nucleicacids in the samples. Thus the methods referred to herein foridentifying elite event EE-GH7 in biological samples, relate to theidentification in biological samples of nucleic acids which comprise theelite event.

As used herein “comprising” is to be interpreted as specifying thepresence of the stated features, integers, steps, reagents or componentsas referred to, but does not preclude the presence or addition of one ormore features, integers, steps or components, or groups thereof. Thus,e.g., a nucleic acid or protein comprising a sequence of nucleotides oramino acids, may comprise more nucleotides or amino acids than theactually cited ones, i.e., be embedded in a larger nucleic acid orprotein. A chimeric gene comprising a DNA sequence which is functionallyor structurally defined, may comprise additional DNA sequences, such aspromoter and transcript termination sequences.

The present invention also relates to the development of an elite eventEE-GH7 in cotton plants comprising this event, the progeny plants andseeds comprising elite event EE-GH7 obtained from these plants and tothe plant cells, or plant material derived from plants comprising thisevent. Plants comprising elite event EE-GH7 can be obtained as describedin Example 1. This invention also relates to seed comprising elite eventEE-GH7 deposited at the ATCC under deposit number PTA-122856 orderivatives therefrom comprising elite event EE-GH7.

“Derivatives (of seed)” as used herein, refers to plants which can begrown from such seed, progeny resulting from crossing or backcrossing,as well as plant cells, organs, parts, tissue, cell cultures,protoplasts, and plant material of same.

Cotton plants or plant material comprising EE-GH7 can be identifiedaccording to any one of the identification protocols for EE-GH7 asdescribed in the Examples, including the PCR Identification Protocoldescribed for EE-GH7 in Example 2.1, the real-time PCR assays asdescribed in Example 2.2, or the end-point TaqMan as described inExample 2.3. Briefly, cotton genomic DNA present in the biologicalsample is amplified by PCR using a primer which specifically recognizesa sequence within the 5′ or 3′ flanking sequence of EE-GH7 such as theprimer with the sequence of SEQ ID NO: 3, SEQ ID No. 5 or SEQ ID No. 11,and a primer which recognizes a sequence in the foreign DNA, such as theprimer with the sequence of SEQ ID No. 4 or SEQ ID No. 6, or with aprimer which recognizes the 5′ or 3′ flanking sequence of EE-GH7 and theforeign DNA contiguous therewith, such as the primer with the sequenceof SEQ ID No. 13. DNA primers which amplify part of an endogenous cottonsequence are used as positive control for the PCR amplification. If uponPCR amplification, the material yields a fragment of the expected sizeor gives rise to fluorescence of the expected fluorescent label, thematerial contains plant material from a cotton plant harboring eliteevent EE-GH7.

Plants harboring EE-GH7 are characterized by their glyphosate tolerance,as well as by their tolerance to HPPD inhibitors such as isoxaflutole.Cotton plants in different commercially available varieties harboringEE-GH7 are also characterized by having agronomical characteristics thatare comparable to the corresponding non-transgenic isogenic commerciallyavailable varieties, in the absence of herbicide application. It hasbeen observed that the presence of a foreign DNA in the insertion regionof the cotton plant genome described herein, confers particularlyinteresting phenotypic and molecular characteristics to the plantscomprising this event.

One embodiment of this invention provides an elite event in cottonplants, obtainable by insertion of 2 transgenes at a specific locationin the cotton genome, which elite event confers tolerance to glyphosateand an HPPD inhibitor herbicide such as isoxaflutole on such cottonplants, and wherein such elite event has an agronomic performanceessentially similar to isogenic lines (as used herein, “isogenic lines”or “near-isogenic lines” are cotton lines of the same genetic backgroundbut lacking the transgenes, such as plants of the same geneticbackground as the plant used for transformation, or segregating sisterlines having lost the transgenes). Particularly, the current inventionprovides an elite event in cotton plants, wherein the insertion orpresence of said elite event in the genome of such cotton plants doesnot appear to cause an increased susceptibility to disease, does notcause a yield penalty or reduced fiber quality, or does not causeincreased lodging, as compared to isogenic lines. Hence, the currentinvention provides an elite event in cotton plants, designated asEE-GH7, which results in cotton plants that can tolerate the applicationof glyphosate and HPPD inhibitor herbicide without negatively affectingthe yield or of fiber quality parameters of said cotton plants comparedto isogenic lines, which cotton plants are not statistically significantdifferent in their disease susceptibility, or lodging, from isogeniccotton plants. These characteristics make the current elite event avaluable tool in a weed resistance management program by providingtolerance to two distinct modes of action in cotton.

Provided herein is also a cotton plant or part thereof comprising eventEE-GH7, wherein representative cotton seed comprising event EE-GH7 hasbeen deposited under ATCC accession number PTA-122856. Further providedherein are seeds of such plants, comprising such event, as well as acotton product produced from such seeds, wherein said cotton productcomprises event EE-GH7. Such cotton product can be cotton fiber or aproduct comprising such cotton fiber. Particularly, such cotton productcomprises a nucleic acid that produces an amplicon diagnostic orspecific for event EE-GH7, such amplicon comprising SEQ ID No. 3 or 4.Also provided herein is a method for producing a cotton product,comprising obtaining a cotton plant or fiber comprising event EE-GH7,and producing such cotton product therefrom.

Also provided herein is a cotton plant, which is progeny of any of theabove cotton plants, and which comprises event EE-GH7.

Further provided herein is a method for producing a cotton planttolerant to glyphosate and/or isoxaflutole herbicides, comprisingintroducing into the genome of such plant event EE-GH7, particularly bycrossing a first cotton plant lacking event EE-GH7 with a cotton plantcomprising EE-GH7, and selecting a progeny plant tolerant to glyphosateand/or isoxaflutole.

Also provided herein is a glyphosate and/or isoxaflutole tolerant plantwith acceptable agronomical characteristics and, particularly havingacceptable fiber quality parameters, comprising a 2mEPSPS and HPPDprotein, and capable of producing an amplicon diagnostic for eventEE-GH7.

Further provided herein is a method for controlling weeds in a field ofcotton plants comprising event EE-GH7, or a field to be planted withsuch cotton plants, comprising treating the field with an effectiveamount of an isoxaflutole-based herbicide, wherein such plants aretolerant to such herbicide.

Further provided herein is a DNA comprising the sequence of SEQ ID No 1or a sequence essentially similar thereto, and any plant, cell, tissueor seed, particularly of cotton, comprising such DNA sequence, such as aplant, cell, tissue, or seed comprising EE-GH7. Also included herein isany cotton plant, cell, tissue or seed, comprising the DNA sequence(heterologous or foreign to a conventional cotton plant, seed, tissue orcell) of SEQ ID No. 1, or comprising a DNA sequence with at least 99% or99.5% sequence identity to the sequence of SEQ ID No. 1.

Also described is a chimeric DNA comprising a foreign DNA, wherein thesequence of said foreign DNA consists of the sequence of SEQ ID No. 1from nucleotide 1218 to nucleotide 8032, flanked by a 5′ and a 3′flanking region, wherein the 5′ flanking region immediately upstream ofand contiguous with said foreign DNA is characterized by a sequenceconsisting of the sequence of SEQ ID No. 1 from nucleotide 1 tonucleotide 1217, and wherein the 3′ flanking region immediatelydownstream of and contiguous with said foreign DNA is characterized by asequence consisting of the sequence of SEQ ID No. 1 from nucleotide 8033to 9328.

Chimeric DNA refers to DNA sequences, including regulatory and codingsequences that are not found together in nature. Accordingly, a chimericDNA may comprise DNA regions adjacent to each other that are derivedfrom different sources, or which are arranged in a manner different fromthat found in nature. A chimeric DNA can consist of the sequence of SEQID No. 1.

Also provided herein is a transgenic cotton plant, plant cell, tissue,or seed, comprising in their genome event EE-GH7 characterized by anucleic acid molecule comprising a nucleotide sequence essentiallysimilar to SEQ ID No. 1 from nucleotide 1207 to nucleotide 1228 and anucleic acid molecule comprising a nucleotide sequence essentiallysimilar to SEQ ID No. 1 from nucleotide 8022 to 8043, or the complementof said sequences, as well as a cotton plant, plant cell, tissue, orseed, comprising in their genome event EE-GH7 characterized by a nucleicacid molecule comprising a nucleotide sequence essentially similar toSEQ ID No. 1, or the complement of said sequences.

The term “isoxaflutole”, as used herein, refers to the herbicideisoxaflutole [i.e.(5-cyclopropyl-4-isoxazolyl)[2-(methylsulfonyl)-4-(trifluoromethyl)phenyl]methanone],the active metabolite thereof, diketonitrile, and any mixtures orsolutions comprising said compounds. HPPD inhibiting herbicides usefulfor application on the event of this invention are the diketonitriles,e.g.2-cyano-3-cyclopropyl-1-(2-methylsulphonyl-4-trifluoromethylphenyl)-propane-1,3-dioneand2-cyano-1-[4-(methylsulphonyl)-2-trifluoromethylphenyl]-3-(1-methylcyclopropyl)propane-1,3-fione;other isoxazoles; and the pyrazolinates, e.g. topramezone [i.e.[3-(4,5-dihydro-3-isoxazolyl)-2-methyl-4-(methylsulfonyl)phenyl](5-hydroxy-1-methyl-1H-pyrazol-4-yl)methanone], and pyrasulfotole[(5-hydroxy-1,3-dimethylpyrazol-4-yl(2-mesyl-4-trifluaromethylphenyl)methanone]; or pyrazofen[2-[4-(2,4-dichlorobenzoyl)-1,3-dimethylpyrazol-5-yloxy]acetophenone].

In one embodiment of this invention, a field to be planted with cottonplants containing the EE-GH7 event, can be treated with an HPPDinhibitor herbicide, such as isoxaflutole (‘IFT’), or with glyphosate,or with both an HPPD inhibitor herbicide and glyphosate, before thecotton is sown, which cleans the field of weeds that are killed by theHPPD inhibitor and/or glyphosate, allowing for no-till practices,followed by planting or sowing of the cottons in that same pre-treatedfield later on (burndown application using an HPPD inhibitor herbicide).The residual activity of IFT will also protect the emerging and growingcotton plants from competition by weeds in the early growth stages. Oncethe cotton plants have a certain size, and weeds tend to re-appear,glyphosate, or an HPPD inhibitor-glyphosate mixture, can be applied aspost-emergent herbicide over the top of the plants.

In another embodiment of this invention, a field in which seedscontaining the EE-GH7 event were sown, can be treated with an HPPDinhibitor herbicide, such as IFT, before the cotton plants emerge butafter the seeds are sown (the field can be made weed-free before sowingusing other means, typically conventional tillage practices such asploughing, chissel ploughing, or seed bed preparation), where residualactivity will keep the field free of weeds killed by the herbicide sothat the emerging and growing cotton plants have no competition by weeds(pre-emergence application of an HPPD inhibitor herbicide). Once thecotton plants have a certain size, and weeds tend to re-appear,glyphosate—or an HPPD inhibitor-glyphosate mixture—can be applied aspost-emergent herbicide over the top of the plants.

In another embodiment of this invention, plants containing the EE-GH7event, can be treated with an HPPD inhibitor herbicide, such as IFT,over the top of the cotton plants that have emerged from the seeds thatwere sown, which cleans the field of weeds killed by the HPPD inhibitor,which application can be together with (e.g., in a spray tank mix),followed by or preceded by a treatment with glyphosate as post-emergentherbicide over the top of the plants (post-emergence application of anHPPD inhibitor herbicide (with or without glyphosate)).

EXAMPLES

1. Transformation of Gossypium hirsutum with Herbicide Tolerance Genes

1.1. Description of the Foreign DNA Comprising the 2mepeps andhppdPf-W336-1 Pa Chimeric Genes

EE-GH7 cotton was developed through Agrobacterium-mediatedtransformation using the vector pTSIH09 containing hppdPf-W336-1 Pa and2mepsps expression cassettes.

(i) The double mutant 5-enol pyruvylshikimate-3-phosphate synthase(2mepsps) gene that encodes for the 2mEPSPS protein. The 2mepsps codingsequence was developed by introducing a point mutation at positions 102(substitution of threonine by isoleucine) and at position 106(substitution of proline by serine) of the wild-type epsps gene clonedfrom maize (Zea mays) (Lebrun et al, 1997 (WO9704103)). Expression ofthe 2mEPSPS protein confers tolerance to glyphosate herbicides.(ii) The hppdPf-W336-1 Pa gene encodes for the HPPD W336 protein. ThehppdPf-W336-1Pa coding sequence was developed by introducing a singlepoint mutation resulting in the replacement of the amino acid glycine336 with a tryptophan of the wild type hppd gene derived fromPseudomonasfluorescens (Boudec et al., 2001, (U.S. Pat. No.6,245,968B1)). Expression of the HPPD W336 protein confers tolerance toHPPD inhibitor herbicides, such as isoxaflutole.

Plasmid pTSIH09 is a plant transformation vector which contains achimeric 2mepsps gene and a chimeric hppdPf-W336-1 Pa gene locatedbetween the right T-DNA border (RB) and the left T-DNA border (LB). Adescription of the genetic elements comprised between the right and leftT-DNA border is given in Table 1 below. The nucleotide sequence isrepresented in SEQ ID No. 1.

1.2. Event EE-GH7

The T-DNA vector pTSIHO9 was introduced into Agrobacterium tumefaciensC58C1Rif (pEHA101) and cotton were selected using spectinomycin andstreptomycin according to methods known in the art.

The Agrobacterium strains were used to transform the cotton var. “Coker312” according to methods known in the art and transgenic plants wereselected in vitro for tolerance to glyphosate (1.0-1.5 mM), followed byregeneration of transformed plant cells into transgenic fertile cottonplants. T0 plants were treated with tembotrione (HPPD-inhibitorherbicides) to select for the expression of the hppdPfw336-1 Pa genes.The surviving plants were then self-pollinated to generate T1 seed.Subsequent T2 to T7 generations were produced through self-pollination.Subsamples of the T1 and T2 plants were sprayed with glyphosate toensure expression of the 2mepsps gene at those generations. In the T3through T7 generations which were grown in the field, each selfedgeneration was sprayed with glyphosate to ensure the expression of the2mepsps gene.

1.2.1 Identification of Elite Event EE-GH7

Elite event EE-GH7 was selected based on an extensive selectionprocedure based on trait efficacy, good expression and stability of theherbicide tolerance genes, and its compatibility with optimal agronomiccharacteristics such as plant height, height to node, boll retention,stand, vigor, fiber length, fiber strength and lint yield wereevaluated. Cotton plants containing this event were selected from a widerange of different transformation events obtained using the samechimeric genes. Parameters used in the selection of this event were: a)acceptable tolerance to isoxaflutole herbicide application in fieldtrials, b) acceptable tolerance to glyphosate herbicide application infield trials, c) an insertion of the herbicide tolerance transgenes at asingle locus in the cotton plant genome, with absence of vectorbackbone, c) overall agronomy similar to the parent plants used fortransformation (maturity, lodging, disease susceptibility, etc.), e) noyield penalty or no change in fiber quality characteristics caused bythe insertion of the transforming DNA (as compared to a correspondingisogenic line without the event, such as the plant line used fortransformation or commercial varieties, grown under the sameconditions), f) stable inheritance of the insert, and g) phenotypicstability.

1.2.1.1 Structural Stability of the Event

Structural stability of EE-GH7 was determined using Southern Blotanalysis in T1, T3, T4, BC1F2 and BC2F3 generations. The results ofthese southern blot analyses demonstrate structural stability of theevent in all tested generations.

1.2.1.2 Inheritance of the Event

Inheritance of the foreign DNA insert was tested in F2, BC1F2 and BC2F2generations by testing the genotype of hppdPfW336-1 Pa and 2mepsps genesby PCR analysis. Segregation ratios determined for three generations ofEE-GH7 cotton confirmed that the hppdPfW336-1 Pa and 2mepsps genescontained within the EE-GH7 insert are inherited in a predictable mannerand as expected for a single insertion. These data are consistent withMendelian principles and support the conclusion that the EE-GH7 eventconsists of a single insert integrated into a single chromosomal locuswithin the cotton nuclear genome.

1.2.1.3 Stability of Protein Expression

Protein expression levels of HPPD W336 and 2mEPSPS proteins weredetermined by sandwich enzyme-linked immunosorbent assay (ELISA) in leafand fuzzy seed samples collected from three generations (T4, T5, andBC2F4) of EE-GH7 cotton.

Mean expression levels of HPPD W336 in leaf at 4-6 Leaf growth stage(BBCH 14-16) across T4, T5, and BC2F4 generation were 442.73, 421.06 and410.89 μg/g DW, respectively. Mean expression levels of HPPD W336 infuzzy seed at maturity growth stage (BBCH 83-97) across the threegenerations were 42.83, 42.45, and 34.97 μg/g DW, respectively.

Mean expression levels of 2mEPSPS in leaf at 4-6 Leaf growth stage (BBCH14-16) across T4, T5, and BC2F4 generations were 1078.03, 1115.46 and1498.30 μg/g DW, respectively. Mean expression levels of 2mEPSPS infuzzy seed at maturity growth stage (BBCH 83-97) across the threegenerations (T4, T5, and BC2F4) were 163.07, 160.49, and 147.80 μg/g DW,respectively. HPPD W336 and 2mEPSPS, respectively, exhibited similarmean expression levels in leaf and fuzzy seed across the threegenerations. Therefore, the protein expression of HPPD W336 and 2mEPSPSwas demonstrated to be stable over three generations.

1.2.1.4 Agronomic Performance and Tolerance to Isoxaflutole (IFT) andGlyphosate (GLY)

In agronomic equivalency trials, plants comprising EE-GH7 performsimilarly to null segregants and wild-type counterparts. Plantscomprising EE-GH7 had normal agronomic characteristics as compared tothe corresponding non-transgenic plants.

Tolerance of plants comprising EE-GH7 to IFT, to glyphosate and tocombinations thereof, was tested at different locations in the field.The plants comprising EE-GH7 showed good tolerance to IFT alone, inparticular when IFT was applied before emergence. Plants comprisingEE-GH7 also show good tolerance to glyphosate applied post emergence,and to a combination of IFT and glyphosate, especially when IFT wasapplied pre emergence and glyphosate was applied post emergence.Importantly, the glyphosate tolerance of plants comprising EE-GH7 isequal to or better than glyphosate tolerance of the elite glyphosatetolerant event EE-GH3 of WO2007/017186. Currently available data appearto indicate a performance which is at least equal to, or better than theperformance of plants comprising EE-GH7 over plants comprising the hppdand epsps chimeric genes as described in WO2013/026740.

To evaluate the agronomic performance of GHB811 cotton under fieldconditions representative of commercial cultivation, a multi-site fieldevaluation was undertaken. The agronomic assessment included 15locations (seven sites conducted in one year and eight sites conductedin another year) representative of diverse cotton growing regions.

All plots within a field site were subjected to the same growingconditions and management (i.e. cultivation, irrigation, fertilizer,maintenance pesticide treatments). Each plot within each field trial wasidentically sized.

The EE-GH7 cotton plots treated with the trait specific herbicidereceived one spray application of each trait-specific herbicide. Oneapplication of IFT was made at a rate of 100.3 to 115.2 grams activeingredient per hectare (g ai/ha) before or shortly after emergence (BBCH00 to 13). One application of GLY was made at a rate of 1067 to 1222 gai/ha at the six to nine leaf growth stage (BBCH 16 to 19).

The following agronomic parameters were measured throughout the growingseason at each field trial site. Data are reported for each individualplot in each field trial.

Continuous Parameters:

-   -   Early Stand Counts    -   Percent Ground Cover    -   Days and Heat Units to First Flower    -   Days and Heat Units to First Open Bolls    -   Percent Open Bolls    -   Final Stand Count    -   Boll Properties    -   Seed Cotton Yield    -   Lint Yield    -   Link (Fiber) Properties

Categorical Parameters:

-   -   Abiotic Stressor Rating    -   Disease Stressor Rating    -   Insect Stressor Rating    -   Boll Type    -   Plant Lodging

Agronomic observations for the non-GM counterpart (Coker 312) werecompared to EE-GH7 cotton not treated with IFT and GLY, and alsocompared to EE-GH7 cotton treated with IFT and GLY.

Statistically significant differences were detected for the continuousparameters Final Stand Count, Seed Cotton Yield, Lint Yield, and Heightto Node Ratio between the non-GM counterpart (Coker 312) and EE-GH7cotton not treated with trait-specific herbicides. Statisticallysignificant differences were also detected for Boll Weight between thenon-GM counterpart and both EE-GH7 cotton entries (treated and nottreated). All mean values of the continuous agronomic parameters ofEE-GH7 cotton (treated or not treated) were within the range of thereference varieties. Thus, statistically significant differences wereconsidered not biologically relevant.

The combined site summary of statistical results for the categoricalparameters of Boll Type, Plant Lodging, four insect stressor ratings,four disease stressor ratings, and four abiotic stressor ratings weredetermined. No statistically significant differences, as defined by CMHtest p-values <0.05, were detected for thirteen of the fourteencategorical parameters. Statistically significant differences wereobserved for the third disease stressor rating between the non-GMcounterpart and both EE-GH7 cotton entries (treated and not treated).All mean values for EE-GH7 cotton (treated or not treated) in the thirddisease stressor rating fell within the range of the reference varietiesand thus statistically significant differences were considered notbiologically relevant.

Based on the agronomic assessment, EE-GH7 cotton demonstrated nobiologically relevant differences from the non-GM counterpart and showedequivalent agronomic performance to non-GM reference varieties.

1.2.2 Identification of the Flanking Regions and Foreign DNA of EliteEvent EE-GH7

The sequence of the regions flanking the foreign DNA comprising theherbicide tolerance genes in the EE-GH7 elite event was determined to beas follows:

1.2.2.1 Right (5′) Flanking Region

The fragment identified as comprising the 5′ flanking region wassequenced and its nucleotide sequence is represented in SEQ ID No. 1,nucleotides 1-1217.

1.2.2.2 Left (3′) Flanking Region

The fragment identified as comprising the 3′ flanking region wassequenced and its nucleotide sequence is represented in SEQ ID No. 1,nucleotides 8033-9328.

1.2.2.3 Foreign DNA Comprising the Herbicide Tolerance Genes of EE-GH7

Confirmed full DNA sequencing of the foreign DNA and flanking DNAsequences in EE-GH7 resulted in the sequence reported in SEQ ID No. 1.The sequence of the foreign DNA of elite event EE-GH7 comprising theherbicide tolerance genes is represented in SEQ ID No. 1, nucleotides1218-8032. This foreign DNA is preceded immediately upstream andcontiguous with the foreign DNA by the 5′ flanking sequence of SEQ ID No1 from nucleotide 1 to 1217 and is followed immediately downstream andcontiguous with the foreign DNA by the 3′ flanking sequence of SEQ ID No1 from nucleotide 8033 to nucleotide 9328.

1.2.2.4 Identification of the Pre-Insertion Plant DNA

Pre-insertion plant DNA was amplified by PCR. The nucleotide sequence ofthe amplified fragment was identified (SEQ ID No. 2). Nucleotides1218-1230 of SEQ ID No. 2 were deleted the EE-GH7 transgenic locus(target site deletion). Nucleotides 1-1217 of SEQ ID No. 2 correspond tothe 5′ flanking sequence of EE-GH7, and nucleotides 1231-2526 of SEQ IDNo. 2 correspond to the 3′ flanking sequence of EE-GH7.

2. Development of Identification Protocols for EE-GH7

2.1. Polymerase Chain Reaction for Detection of the EE-GH7 EventSpecific Sequence

2.1.1 Primers

Specific primers were developed which recognize sequences within theelite event.

A primer was developed which recognizes a sequence within the 5′flanking region of EE-GH7. A second primer was then selected within thesequence of the foreign DNA so that the primers span a sequence of about126 nucleotides. The following primers were found to give clear andreproducible results in a PCR reaction on EE-GH7 DNA:

Forward primer targeted to the 5′ flanking sequence: PRIM0728:(SEQ ID No.: 3) 5′-CTCCgAATAgTTCCATCAATTTTATCA-3′Reverse primer targeted to the foreign DNA: PRIM0643: (SEQ ID No.: 4)5′-TgATCgggCCTTAATTAACCC-3′

Preferably, an appropriate taxon-specific reference system reaction mustbe performed on identical amounts of DNA of all samples analysed todemonstrate that the samples are in principle functional for PCRanalysis. Such taxon-specific reference system may consist of primerstargeting an endogenous sequence which are included in the PCR cocktail.These primers serve as an internal control in unknown samples and in theDNA positive control. A positive result with the endogenous primer-pairdemonstrates that the samples are in principle functional for PCRanalysis and there is ample DNA of adequate quality in the genomic DNApreparation for a PCR product to be generated.

2.1.2 Amplified Fragments

The expected amplified fragments in the PCR reaction are:

For primer pair PRIM0728-PRIM0643: 126 bp (EE-GH7 elite event)

2.1.3 Template DNA

Template DNA was be prepared using the AGOWA sbeadex Maxi Plant Kit.When using DNA prepared with other methods, a test run utilizingdifferent amounts of template should be done. Usually 50 ng of genomictemplate DNA yields the best results.

2.1.4 Assigned Positive and Negative Controls

To avoid false positives or negatives, it was determined that thefollowing positive and negative controls should be included in a PCRrun:

-   -   No template control (DNA negative control). This is a PCR in        which no DNA is added to the reaction. When the expected result,        no PCR products, is observed this indicates that the PCR        cocktail was not contaminated with target DNA.    -   A positive DNA control (genomic DNA sample known to contain the        transgenic sequences). Successful amplification of this positive        control demonstrates that the PCR was run under conditions which        allow for the amplification of target sequences.    -   A negative DNA control (wild-type DNA control). This is a PCR in        which the template DNA provided is genomic DNA prepared from a        non-transgenic plant. When the expected result, no amplification        of the event specific PCR product but amplification of the        endogenous PCR product, is observed this indicates that there is        no detectable transgene background amplification in a genomic        DNA sample.

2.1.5 PCR Conditions

Optimal results were obtained under the following conditions (Indescribing the various conditions for optimal results is meant toprovide examples of such conditions. Clearly one skilled in the artcould vary conditions, reagents and parameters such as using other Taqpolymerases, and achieve desirable results):

-   -   the PCR mix for 25 μl reactions contains:        -   50 ng template DNA        -   5.0 μl 5× Amplification Buffer (supplied by the manufacturer            with the Taq polymerase)        -   0.25 μl 20 mM dNTP's        -   0.7 μl PRIM0728 (10 pmoles/μl)        -   0.7 μl PRIM0643 (10 pmoles/μl)        -   0.1 μl Taq DNA polymerase (5 units/μl)        -   water up to 25 μl    -   the thermocycling profile to be followed for optimal results is        the following:

4 min. at 95° C. Followed by: 1 min. at 95° C. 1 min. at 60° C. 2 min.at 72° C. For 5 cycles Followed by: 30 sec. at 92° C. 30 sec. at 60° C.1 min. at 72° C. For 30 cycles Followed by: 10 minutes at 72° C.

2.1.6 Agarose Gel Analysis

To optimally visualize the results of the PCR it was determined thatabout 25 μl of the PCR samples should be applied on a 3% agarose gel(Tris-borate buffer, ethidiumbromide stained) with an appropriatemolecular weight marker (e.g. 50 bp ladder).

2.1.7 Validation of the Results

It was determined that data from transgenic plant DNA samples within asingle PCR run and a single PCR cocktail should not be acceptableunless 1) the DNA positive control shows the expected PCR product(transgenic fragment and, if included, endogenous fragment), 2) the DNAnegative control is negative for PCR amplification (no fragment), and 3)the wild-type DNA control is negative for PCR amplification for thetransgenic fragment and, if included, positive for the endogenousfragment.

When following the PCR Identification Protocol for EE-GH7 as describedabove, lanes showing visible amounts of the transgenic PCR products ofthe expected sizes, indicate that the corresponding plant from which thegenomic template DNA was prepared, has inherited the EE-GH7 elite event.Lanes not showing visible amounts of the transgenic PCR product indicatethat the corresponding plant from which the genomic template DNA wasprepared, does not comprise the elite event.

2.1.8 Use of Discriminating PCR Protocol to Identify EE-GH7

Before attempting to screen unknowns, a test run, with all appropriatecontrols, is performed. The developed protocol might requireoptimization for components that may differ between labs (template DNApreparation, Taq DNA polymerase, quality of the primers, dNTP's,thermocyler, etc.).

Leaf material from a number of cotton plants, some of which comprisingEE-GH7 were tested according to the above-described protocol. Samplesfrom elite event EE-GH7 and from cotton wild-type were taken as positiveand negative controls, respectively.

FIG. 2 illustrates the result obtained with the elite event PCRIdentification Protocol for EE-GH7 on a number of cotton plant samples.The samples in lanes 2, 3, 4, 11, 12 and 13 represent the negativecontrol (no template); lanes 5, 6 and 7 contain DNA from wild typecotton plants. Lanes 8, 9 and 10 comprise samples from cottontransformation event EE-GH7, lanes 1 and 14 represent the MolecularWeight Marker (50 bp ladder). It can be seen that, specifically forcotton transformation event EE-GH7, a 126 bp PCR fragment is produced.

2.2. Real-Time PCR Assay for Detection of the EE-GH7 Event SpecificSequence

2.2.1 Real-Time PCR Assay for EE-GH7 Detection in Bulked Seeds

A Real-Time PCR assay is set up to detect low level presence of EE-GH7in bulked seeds.

The following primers were applied in this target PCR reaction:

Forward primer targeted to the 5′ flanking sequence: PRIM0638(SEQ ID No. 5) 5′-CgAATAgTTCCATCAATTTTATCATTTATg-3′Reverse primer targeted to the foreign DNA sequence: PRIM0639(SEQ ID No. 6) 5′-TCgggCCTTAATTAACCCg-3′

The expected amplified fragment in the PCR reaction from these primersis 120 bp.

Probe targeted to the junction 5′ flanking— foreign DNA sequence: TM1576(SEQ ID No. 7) 5′-AgAACAACAgTACTgggC-3′

The TM1576 probe is labelled with FAM at the 5′ end and with thenon-fluorescent quencher MGBNFQ at the 3′ end.

The target PCR reaction is performed on approximately 200 ng of templateDNA prepared using the AGOWA sbeadex Maxi Plant Kit. When using DNAprepared with other methods, a test run using samples with knownrelative levels of EE-GH7 should be performed.

An appropriate taxon-specific reference system reaction must beperformed on identical amounts of DNA of all samples analysed todemonstrate that the samples are in principle functional for PCRanalysis.

For unknown test samples the PCR experiment should ideally include theappropriate positive and negative control samples, i.e.:

-   -   No template control (DNA negative control). This is a PCR in        which no DNA is added to the reaction. When the expected result        (no PCR product) is observed for both the target and the        reference system reaction this indicates that the PCR cocktail        was not contaminated with target DNA.    -   A positive DNA control (genomic DNA sample known to contain the        transgenic sequences). Successful amplification of this positive        control demonstrates that the PCR was run under conditions which        allow for the amplification of target sequences.    -   Also a negative DNA control (wild-type DNA control) can be added        in this PCR. This is a PCR in which the template DNA provided is        genomic DNA prepared from a non-transgenic plant. When the        expected result, no amplification of a transgene PCR product but        amplification of the endogenous PCR product, is observed this        indicates that there is no detectable transgene background        amplification in a genomic DNA sample.

This protocol was validated using 2× PerfeCta qPCR Fastmix II, Low ROXsupplied by Quanta Bioscience (catalog nr. 95120). Any other reactionbuffer may be applied but the procedures need to be validatedsuccessfully with the appropriate set of positive and negative controlsprior to analyzing samples of unknown content. Optimal results areobtained under the following conditions:

-   -   the PCR mix for 20 μl reactions contains:        -   200 ng template DNA        -   10 μl 2× PerfeCta qPCR Fastmix II, low ROX (Quanta            Biosciences)        -   0.5 μl PRIM0638 (10 pmoles/μl)        -   0.5 μl PRIM0639 (10 pmoles/μl)        -   0.5 μl TM1576 (10 pmoles/μl)        -   Add water up to 20 μl    -   the thermo-cycling profile to be followed for optimal results is        the following:

5 min. at 95° C. Followed by: 15 sec. at 95° C. 1 min. at 60° C. For 40cycles

Amplification of the target is measured real-time by measuring the FAMreporter dye during the step of 1 min. at 60° C.

Results of the Real-Time PCR Identification Protocol for EE-GH7 for5-fold dilutions of genomic DNA comprising EE-GH7 are shown in FIG. 3.FIG. 3 shows that there is a clear correlation between the PCR cycle atwhich the threshold level is reached and the dilution of the DNAcomprising EE-GH7.

2.2.2 Copy Real-Time PCR Assay for EE-GH7 for Determination of thePresence and the Zygosity on Individual Plants/Single Seeds

A copy Real-Time PCR assay is set up to quantify the presence of EE-GH7and to determine the zygosity of EE-GH7 in individual plants/singleseeds.

The primers and probe applied in this target PCR reaction directed tothe transgene DNA sequence are the same as described for the Real-TimePCR assay for EE-GH7 detection in bulked seeds as described in Example2.2.1.:

Forward primer targeted to the 5′ flanking sequence: PRIM0638(SEQ ID No. 5) 5′-CgAATAgTTCCATCAATTTTATCATTTATg-3′Reverse primer targeted to the foreign DNA sequence: PRIM0639(SEQ ID No. 6) 5′-TCgggCCTTAATTAACCCg-3′

The expected amplified fragment in the PCR reaction from these primersis 120 bp.

Probe targeted to the junction 5′ flanking—foreign DNA sequence:

TM1576 (SEQ ID No. 7) 5′-AgAACAACAgTACTgggC-3′

The TM1576 probe is labelled with FAM at the 5′ end and with thenon-fluorescent quencher MGBNFQ at the 3′ end.

The following primers targeting an endogenous sequence are also includedin the PCR cocktail. These primers serve as an internal control inunknown samples and in the DNA positive control. A positive result withthe endogenous primer-pair (presence of an PCR amplified fragment of 74bp) demonstrates that there is ample DNA of adequate quality in thegenomic DNA preparation for a PCR product to be generated. Suitableendogenous primers can be primers selected to recognize a housekeepinggene in cotton, such as:

Forward primer targeted to an endogenous target gene sequence: KVM157:(SEQ ID No.: 8) 5′-CACATgACTTAgCCCATCTTTgC-3′Reverse primer targeted to an endogenous target gene sequence: KVM158:(SEQ ID No.: 9) 5′-CCCACCCTTTTTTggTTTAgC-3′

The expected amplified fragment in the PCR reaction from these primersis 74 bp.

Probe targeted to endogenous target gene sequence:

TM1304: (SEQ ID No.: 10) 5′-TgCAggTTTTggTgCCACTgTgAATg-3′

The TM1304 probe is labelled with JOE at the 5′ end and with thenon-fluorescent quencher BHQ1 at the 3′ end.

This protocol was validated using 2× PerfeCta qPCR Fastmix II, Low ROXsupplied by Quanta Bioscience (catalog nr. 95120). Any other reactionbuffer may be applied but the procedures need to be validatedsuccessfully with the appropriate set of positive and negative controlsprior to analysing samples of unknown content. Optimal results areobtained under the following conditions:

-   -   the PCR mix for 10 μl reactions contains:        -   10 ng template DNA        -   5 μl 2× PerfeCta qPCR Fastmix II, low ROX (Quanta            Biosciences)        -   0.5 μl PRIM0638 (10 pmoles/μl)        -   0.5 μl PRIM0639 (10 pmoles/μl)        -   0.5 μl KVM157 (10 pmoles/μl)        -   0.5 μl KVM158 (10 pmoles/μl)        -   0.1 μl TM1576 (10 pmoles/μl)        -   0.1 μl TM1304 (10 pmoles/μl)            Add water up to 10 μl    -   the thermocycling profile to be followed for optimal results is        the following:

5 min. at 95° C. Followed by: 3 sec. at 95° C. 30 sec. at 60° C. For 35cycles

Amplification of the target is measured real-time by measuring the FAMreporter dye during the step of 30 sec. at 60° C. and amplification ofthe endogenous control is measured real-time by measuring the JOEreporter dye during the step of 30 sec. at 60° C.

To avoid false positives or negatives, it was determined that thefollowing positive and negative controls should be included in a PCRrun:

-   -   Homozygous control: a genomic DNA sample containing the target        sequence described homozygously    -   Hemizygous control: a genomic DNA sample containing the target        sequence described hemizygously    -   Wild type control (DNA negative control): a genomic DNA sample        not containing the target sequence described    -   No Template Control (NTC): a water sample

Data analysis was performed using the ddCt method. In this method thezygosity for each test sample is calculated relative to a referencesample. For DNA samples hemizygous for EE-GH7, a copy number of 1 wascalculated, whereas for DNA samples homozygous for EE-GH7 a copy numberof 2 was calculated using this method, showing that it can be used todetermine the zygosity status of EE-GH7.

2.3. End-Point TaqMan for Detection of the EE-GH7 Event SpecificSequence

The End-point TaqMan for EE-GH7 detection uses the same primers andprobes as the copy Real-Time PCR assay for EE-GH7 detection onindividual plants/single seeds as described under 2.2.2.

-   -   the PCR mix for 10 μl reactions contains:        -   10 ng template DNA        -   5 μl 2× PerfeCta qPCR Fastmix II, low (Quanta Biosciences,            cat no 95119)        -   0.5 μl PRIM0638 (10 pmoles/μl)        -   0.5 μl PRIM0639 (10 pmoles/μl)        -   0.04 μl KVM157 (10 pmoles/μl)        -   0.04 μl KVM158 (10 pmoles/μl)        -   0.1 μl TM1576 (10 pmoles/μl)        -   0.05 μl TM1304 (10 pmoles/μl)            Add water up to 10 μl    -   the thermocycling was the following:

5 min. at 95° C. Followed by: 3 sec. at 95° C. 30 sec. at 60° C. For 35cycles

Results for an end-point TaqMan PCR Identification Protocol for EE-GH7detection are shown in FIG. 4. It is shown that samples comprisingEE-GH7 (samples A1-A8) contain the EE-GH7 signal as well as theendogenous control signal above the threshold; the samples containingnon-transformed cotton (samples A9 and A10) contain only endogenouscontrol, but not EE-GH7 signal above the threshold, and the no templatecontrol (samples A11-A12) contain no signal above the threshold.

3. Protocol for the PCR-Based Determination of the Zygosity Status ofEE-GH7

3.1. Primers

Two primers recognizing the nucleotide sequences of the wild-type locusprior to insertion of the elite event, were designed in such a way thatthey are in a direction towards each other, and one primer is located inthe region corresponding to the 5′ or 3′ flanking region of the event,and one primer is directed to the junction sequence of the target sitedeletion in the pre-insertion locus, and the 3′ or 5′ flanking region,respectively. A third primer is included which is targeted to thejunction sequence of the foreign DNA in the transgenic locus, and the 3′or 5′ flanking region, respectively. Presence of these three primersallows simultaneous PCR amplification of the EE-GH7 specific sequence aswell as of the wild type sequence.

The following primers were found to give particularly clear andreproducible results in a zygosity scoring PCR reaction on EE-GH7 DNA:

PRIM0726: (SEQ ID No.: 11) 5′-CAAACTCCgAATAgTTCCATCAATTT-3′(target: Plant DNA of the 5′ flanking sequence) PRIM0733(SEQ ID No.: 12) 5′-gAAggTCggAgTCAACggATTgCTTACTTAAgCATTgTTCTgTTTCAAg-3′ (target: 5′flanking target site deletion junctionsequence (nt 22-49 of SEQ ID No. 12) extended with a 5′tail (nt 1-21 of SEQ ID No. 12)). PRIM0731 (SEQ ID No.: 13)5′-gAAggTgACCAAgTTCATgCTggCCCAgTACTgTTgTTCTgTTT C-3′(target: 5′flanking foreign DNA junction sequence(nt 22-45 of SEQ ID No. 13) extended with a 5′tail (nt 1-21 of SEQ ID No. 13)).

3.2. Amplified Fragments

The expected amplified fragments in the PCR reaction are:

For primer pair PRIM0726-PRIM0733: 76 bp (wild-type locus)For primer pair PRIM0726-PRIM0731: 71 bp (EE-GH7 locus)

3.3. Template DNA

Template DNA was prepared using the AGOWA sbeadex Maxi Plant Kit. Whenusing DNA prepared with other methods, a test run utilizing differentamounts of template should be done. Between 5 and 80 ng of genomictemplate DNA can be used.

3.4. Assigned Positive and Negative Controls

To avoid false positives or negatives, it is advisable that thefollowing positive and negative controls should be included in a PCRrun:

-   -   Homozygous control: a genomic DNA sample containing the target        sequence described homozygously    -   Hemizygous control: a genomic DNA sample containing the target        sequence described hemizygously    -   Wild type control (DNA negative control): a genomic DNA sample        not containing the target sequence described    -   No Template Control (NTC): a water sample

3.5. PCR Conditions

Optimal results were obtained under the following conditions. Obviously,other Taq polymerases can be used, and then the conditions can differ tofollow supplier recommendations.

-   -   the PCR mix for 10 μl reactions contains:        -   x μl template DNA (20 ng)        -   5.0 μl KASPar v3.0 Reagent (96-384 well formulation) (LGC)        -   0.14 μl assay mix        -   water up to 25 μl    -   100 μl assay mix contains:        -   12 μl PRIM0731 (100 pmol/μl)        -   12 μl PRIM0733 (100 pmol/μl)        -   30 μl PRIM0726 (100 pmol/μl)        -   water up to 100 μl            the KASPar v3.0 reagent contains a FRET cassette labelled            with VIC dye corresponding to the tail of PRIM0733            (wild-type specific primer), and a FRET cassette labelled            with FAM dye corresponding to the tail of PRIM0731 (EE-GH7            specific primer).    -   the thermocycling profile to be followed for optimal results is        the following:

15 min. at 94° C. Followed by: 20 sec. at 94° C. 1 min. at 65° C. (−0.8°C./cycle) For 10 cycles Followed by: 20 sec. at 94° C. 1 min. at 57° C.For 26 cycles

3.6. Data Analysis

For all samples, fluorescent Signal to Background ratio's (S/B) arecalculated for both the event specific and the wild type locusreactions. The background level is determined by the NTC samples.

Results of test samples are only valid if the control samples give theexpected results, ie:

-   -   The homozygous control is scored “homozygous”    -   The hemizygous control is scored “hemizygous”    -   The wild type control is scored “wild type”    -   The NTC's only show fluorescent background levels

A sample is scored:

-   -   “Homozygous”: if the sample is located in the homozygous cluster        and the S/B exceeds the minimum acceptance S/B ratio (i.e. FAM        S/B ratio)    -   “Hemizygous”: if the sample is located in the hemizygous cluster        and the S/B exceeds the minimum acceptance S/B ratio (i.e. FAM        and VIC S/B ratio)    -   “Wild type”: if the sample is located in the wild type cluster        and the S/B exceeds the minimum acceptance S/B ratio (i.e. VIC        S/B ratio)    -   “Non-conclusive”: if the sample is located in between the 3        clusters or if the S/B is lower than the minimum acceptance S/B        ratio

An example of S/B ratios for material from homozygous lines for EE-GH7,for material from lines hemizyous for EE-GH7, and for wild-type lines isshown in FIG. 5. It can be seen that only VIC, but no FAM is measured inwild-type material (located in the wild type cluster and the S/B exceedsthe minimum acceptance S/B ratio), both VIC and FAM are measured inmaterial hemizyous for EE-GH7 (located in the hemizygous cluster and theS/B exceeds the minimum acceptance S/B ratio), and only FAM is measuredfor material homozygous for EE-GH7 (located in the homozygous clusterand the S/B exceeds the minimum acceptance S/B ratio).

4. Introgression of EE-GH7 into Preferred Cultivars

Elite Event EE-GH7 was introduced by repeated back-crossing into cottonvariety ST 457. Agronomic performance was determined for EE-GH7 in theST 457 background and in the Coker 312 background in the field at fourdifferent locations. Plants were treated with 210 g IFT (2×) preemergence, with 210 g IFT (2×) post emergence Early (E; 2-4 leaf stage),with 4244 g Roundup PowerMax (2×) post emergence Early (E; 2-4 leafstage), Mid (M; between squaring and before bloom) and Late (L; Bloom),with 210 g IFT+4244 g Roundup PowerMax (2×) post emergence, or with 210g IFT pre-emergence followed by 4244 g Roundup Powermax post emergence.Agronomic parameters were compared to the respective untreated plantswith the same background but not comprising EE-GH7. For only onetreatment, a significant difference in lint yield was observed betweenuntreated control plants and plants comprising EE-GH7 (210 g IFT+4244 gRoundup PowerMax (2×) post emergence). This was however due to adifference observed at one location only; at the other four locations,there was no significant difference between untreated control plants andplants with the same genetic background but not comprising EE-GH7. Forall other treatments, the lint yield in plants comprising EE-GH7 was notsignificantly different from the lint yield of the untreated controlplants. This shows that in the Coker 312 background and in the ST 547background, the lint yield of plants comprising EE-GH7 treated withdifferent combinations of herbicides is highly equivalent to lint yieldof untreated control plants not comprising the event.

Agronomic equivalency was tested by comparing different agronomicparameters for plants comprising EE-GH7 with null-segregants and withwild-type (not comprising EE-GH7) plants at four locations. In the ST457 background, length, POB (percent open bolls), LP (lint percentage),SI (seed index) was not significantly different from both wild type andnull segregants. Uniformity of plants comprising EE-GH7 in the ST 457background was significantly higher than both wild type controls andnull segregants, and lint yield was significantly higher than for thenull segregant but not than the wild type. In the Coker 312 background,there was some fluctuation in performance, resulting in a slightly lowerlint yield and lint percentage as compared to the wild type. This lowerlint yield and lint percentage was however not observed as compared tothe null segregant, indicating it was not due to the presence of theevent. All other parameters in the Coker 312 background were notsignificantly different. In summary, these data show that the plantscomprising EE-GH7 behave for different agronomic parameters very similarto isogenic plants not comprising EE-GH7.

Elite Event EE-GH7 was introduced by repeated back-crossing into cottonvarieties 05M0201 and 11A, in which it was stacked with the eventsT304-40, comprising glufosinate tolerance and the Cry1Ab gene asdescribed in WO2008/122406, GHB119 comprising glufosinate tolerance andthe Cry2Ae gene as described in WO2008/151780, and COT102 comprising theVIP3A gene as described in WO2004/039986. Plants were treated with 105 gIFT (IX) pre-emergence, 210 g IFT (2×) pre emergence, with 105 g IFT(1×) post emergence, with 210 g IFT (2×) post emergence, with 4244 gRoundup PowerMax (2×) post emergence (E, M and L), with 210 g IFTpre-emergence followed by 4244 g Roundup PowerMax (2×) post emergence,with 1761 g Liberty (2×) post emergence (E and M), with 210 g IFT (2×)pre emergence followed by 1761 g Liberty (2×) post emergence (E and M),or with 210 g IFT (2×) pre-emergence and 1761 g Liberty (2×) postemergence. Agronomic parameters were compared to plants with therespective background but not comprising EE-GH7 across 8 locations. Onlyfor one treatment and one parameter (lint length in the treatment with210 g IFT pre-emergence followed by 4244 g Roundup PowerMax (2×) postemergence) lint length was significantly higher than of the control.Lint length was not significantly different between plants comprisingEE-GH7 and the control plants for any of the other treatments. For allthe other parameters tested (lint yield, micronaire, strength, and finalplant height), and for all treatments, there was no significantdifference between plants comprising EE-GH7 and the control plants.These data show that the plants comprising EE-GH7 behave, in differentcommercial backgrounds, for different agronomic parameters very similarto isogenic plants not comprising EE-GH7. Moreover, the presence ofEE-GH7 does not impact the tolerance to glufosinate (Liberty) conferredby T304-40 and GHB119, nor does it affect the expression of the Bt genes(Cry1Ab, Cry2Ae, VIP3A).

Agronomic equivalency of plants comprising EE-GH7 in cotton varieties05M0201m 11A, and 04SC095, all comprising T304-40, GHB119 and COT102 asdescribed above, was tested by comparing different agronomic parametersfor plants comprising EE-GH7 with null-segregants and with parentmaterial for 05M0201, 11A and 04SC095 plants not comprising EE-GH7 atfour locations. It was found that the plants comprising EE-GH7 performsimilarly to null segregants in agronomic equivalency trials.

It is observed that the introgression of the elite event into thesecultivars does not significantly influence any of the desirablephenotypic or agronomic characteristics of these cultivars (no linkagedrag) while expression of the transgene, as determined by glyphosateand/or isoxaflutole tolerance, meets commercially acceptable levels.This confirms the status of event EE-GH7 as an elite event.
